The Implementation of Employee Attendance System based on ZigBee technology using LAN Networking over Traditional Biometric Systems

In the present days, most of the attendance systems of offices, institutes, universities, schools, colleges etc. has been converted into biometric systems. But, this traditional biometric systems can be updated with Zigbee technology for better performance and output. In this paper provides the design method of wireless fingerprint employee attendance system based on ZigBee technology using LAN networking. The system includes terminal fingerprint acquisition module and attendance management module through computer. It can realize automatically such functions as information acquisition of fingerprint, processing, wireless transmission, fingerprint matching, and attendance management. Considering the fact and topology of ZigBee network, a fingerprint acquisition module and a wireless alarm module were designed by using the fingerprint sensor and module respectively. The whole system was implemented wireless alarm through messages and internet in the GSM web. All HODs PCs are worked as workstation and LAN connected with the Director�s office. In order to achieve the simple and high real-time system, it realized low-cost and high-performance wireless fingerprint attendance function, which provided a new wireless fingerprint attendance system for enterprises and institutions.
